Real-time MRI
has the potential to enable many intraoperative surgical processes, but there
is a great need within the MR community for extensible software platforms
that can allow rapid development of tools for MR guided procedures. One such
platform is based upon the RTHawk system for real-time acquisition and
reconstruction and the Vurtigo system for interactive visualization. We use
this platform to develop a system for performing targeted intracerebral
infusions under MRI guidance. Initial testing of our system in phantoms and
ex vivo brains has shown targeting accuracy on the order of 1-2 mm.
